Stay away from LEVOIT.
I bought 3 units of the Core 200S-P on amazon, about 2 weeks ago and I can say they are useless with home assistant. The app “VeSync” on my iPhone would lose connection to the network for several hours a day leaving the device unable to be controlled trough the oficial app (VeSync) or Home Assistant integration, so I decided to contact support believing that was some sort of bug / issue that could be addressed with an update, unfortunately I discovered that the app is intentionally limiting the requests you can do per day and this is a very strict number and to make things even worse I believe this limit is per user and not devices (they all lose network and come back up together) and the fact that I have 3 units only aggravates the problem.
Here is the e-mail reply I got from them:
" Thank you for reaching out! I’m sorry to hear that you’re experiencing connection issues with your Air Purifier Core 200S-P units. I understand how frustrating this can be, and I’m here to help.
-
Request Rate Limiting: Due to company policy, we have implemented rate limiting on the app to prevent malicious requests. If the number of requests exceeds a certain limit, the app will temporarily become unusable until the next day.
-
Exiting the App: When you’re not actively using the app, I recommend fully exiting it (this means closing the app completely, not just logging out) to avoid unnecessary requests.
-
Home Screen Activity: Please avoid leaving the app open on the Home screen for extended periods. Staying on this screen causes the device list to send requests every 15 seconds, which can lead to connection issues. If you navigate away from the device list, these repeated requests won’t occur.
-
Third-Party Account Management: If you are using any scripts or logging into your VeSync account through third-party services, please log out of those accounts as well.
If you continue to have issues after trying these suggestions, please let me know, and we can explore further options. I want to ensure you’re satisfied with your purchase!
Best regards,"
Not only this, LEVOIT fails to clearly advertise its HEPA filter capability as you can see here. And claim on the Amazon website this air purifier works on rooms up to 916 Sq.Foot while I found the same unit selling at the Target store claiming to work on rooms up to 182 Sq.Foot.
